Abstract
We analyse the role of the wage scope defined by the manufacturing sector in the history of wage coordination in Norway. Using econometric methods, we document a long-term empirical equation that link the national annual wage to the manufacturing-sector wage scope, defined as the value of labour productivity, and which is known as the ’main-course’. Tests of exogeneity support the interpretation of the main-course as a long-run driver of the national annul wage. Contributing to the literature on the wage–productivity nexus, we show that the productivity component of the main-course has been the dominant determinant of the secular growth in the purchasing power of annual wages. Changes in the relative price of manufacturing value added and consumer goods have played a subsidiary role, together with unemployment and reductions in annual working time. Identified structural breaks cluster in the 1920s and 1930s, reflecting economic crises and institutional change, while the estimated relationship remains consistent with Norway’s contemporary pattern wage bargaining system.
